Here is a handy list of project ideas that CircuitBrains could be used in:

• Attach some sensors and make an environmental monitor
• Home automation sensor brains
• Hook it into some stepper drivers and move some motors
• Add an antenna circuit and use it to send or receive RF data
• Do some 3D printing around CircuitBrains and a servo to dispense hand sanitizer
• Use the DAC on it to produce some sound through an amplifier
• Build a reflow oven with a PID and a solid state relay
• Attach it to a computer and use it as a HID device
• Attach a couple buttons and a display and make a scoreboard for a game
• Make an electronic badge
• Make a digital alarm clock
• Build a quirky random number generator
• Add a GPS breakout and capture positioning data
• Add a display and a couple of buttons and make a retro game system
• Add a liquid flow meter, hook it onto a sink or toilet and record how much water you use
